APEC Tankless RO Water Filter System ROTL-AIO - Four-in-One Premium Reverse Osmosis Water Filtration, 2:1 Pure to Drain, Filters Fluoride, Heavy Metals, 1K+ Impurities, Easy DIY Install & Care

This is a good product, i have used couple other products in the past and the quality is top notch. Well packaged,Easy install, pump is quite, water is clean! Would recommend 100%

We bought the unit a month ago and had some trouble with the power unit. APEC took care of it and the overall installation was a breeze. The water tastes amazing and gives us peace of mind since we're very concerned about forever chemicals (PFAS). Super happy with customer service and product.

Bought directly from the manufacturer, item arrived well packaged. The filter is larger than most commonly used RO filters - but it is all in one. Having one filter to change every year is easier for maintenance rather than keeping track of schedule for each filter separately. Materials included are of good quality and the manual for installation is clear and concise. I was able to install the system in an hour or so, with no previous experience. The noise when the motor turns on is not too concerning. Glad that it comes with an indicator to alert on water leak and hoping that it works as expected. The filter life indicator is on the unit. This is a minor inconvenience, as the under-sink cabinet is mostly closed, and you might not notice it alerting for a while. Right after turning on the faucet - first few glasses of water might have a larger ppm, and it gets better as the system pushes more water through the system. This kind of adds a delay to get purified water every-time. But this is an OK compromise to get a sleek, tankless system. Customer service so far has been quite responsive over emails, hope it continues! Please consider providing multiple options for faucet. I would have chosen a Chrome option, if available to match with the kitchen faucet.

I purchased the APEC tankless system, and its the most substantial upgrade I've made to my apartment and my quality of life in a decade. I appreciate the certifications and third party testing because the quality of my water isn't negotiable. The install was straightforward, the system is beautifully built, and the water iI get from it is incredible. All that's to say, I'm extremely satisfied, and offer my highest endorsement of this product and company.

Have been using my new APEC system for a couple weeks, and love it! No tank, so fits under sink nicely, and you only hear it when it is in use. I had a plumber install it, and he was impressed with it, too. It appears changing filters will be easy as well. Look forward to many years of pure water. R. David Campbell, M.D.

I spent months researching the best tankless Reverse Osmosis system, in my opinion Apex has knocked it out of the park. Installation was a breeze. Love the extra space now in my cabinet and the unit looks fantastic. Most Reverse Osmosis system waste upwards of 10 to 1, are you serious? Ten gallons of water down the drain for one clean gallon? YEPS Now 2 gallons of clean to one gallon of waste water. It has enough water pressure to run my ice maker as well. You will hear noise from the pump when the unit is being used, nothing that it concerning.

I've had this for a few weeks now and it works great. Super easy to install and use. My only complaint is that it sounds a bit like a jackhammer when it makes contact with the bottom of the cabinet and runs. Probably due to the area underneath being hollow and it amplifying the noise. Though this is the design of most cabinets. If they included a rubber/foam pad or something to help isolate it I think it would really help this. I've put a piece of foam underneath it and that really dulled the noise

I replaced my RO-90 with the new ROTL-AIO. The new unit frees up a lot of under-the-counter-space. Nevertheless, it does not perform as well in filtering our water as the RO-90 did. The first water from the tap tests at 150 ppm. After running for thirty seconds, it will test at 30-35 ppm. When I disconnected the RO-90, the water tested at 22 ppm--on tired filters. With fresh filters, water samples test in the low teens. For reference, our Colorado river water test typically between 450 and 500 ppm, depending upon the season. I do like the faucet better on the R0-90. The extra inch-and-a-half in height made it easier to fill up my large pasta pot from the counter. The ROTL filter seems easy to install and remove, and much less messy that on the RO-90. The installation instructions are not very clear at several points. I'm glad I had experience installing an Ro-90. I am generally very impressed with APEC products. They seem well engineered and manufactured--well thought out from the consumer's perspective. The ROTL does not quite live up to these standards

Very pleased with this purchase. Takes up way less room than the previous unit that required a separate tank and the filter set up. Great flow. Only drawback is noise when in use. It is not very loud and only when in use. Single filter to replace will be great!

After having my previous apec water system for almost 3 years, I decided to upgrade due to a leak in my old system. While the tankless system takes up less room which is nice, please consider that this system needs electrical power. The new system also seems to be extremely sensitive to its functions, and troubleshooting can be repudiative. I also literally had to let my water run a full 30 minutes to set the filter to correct function. That is a lot of wasted water. I also think comparatively the water coming from the tankless system does not taste as good as my older apec system. While the benefits of space saving are there I was much happier with my previous set up.
